Progress System Tables Guide

Written by Dan Foreman, Current Edition: October 2011

Virtual System Tables (VST's) were added in V8.2. VST's provide access to data that was previously only accessible through the promon utility. The Progress documentation gives a basic description of each Virtual System Table (VST) but is generally inadequate for anyone attempting to do so serious work with VST's.
